DEVICE DIAGNOSTICS Sub-menu
In the event that the System Diagnostics fails, the Generator Diagnostics
(Pulse Generator Test), which uses the resistor assembly connected at
implantation, verifies proper Pulse Generator operation.
When you select any of the four diagnostics tests from the DEVICE
DIAGNOSTICS Sub-menu, additional instructions will be provided on the
handheld screen. These instructions vary for each selection. Follow them
carefully.
Because delivery of an output stimulation is required for diagnostic data
collection, the Programming Software will automatically program the
output current at the initiation of a Generator or System diagnostic tests.
The automatic programming is not performed for the Magnet or Normal
Mode diagnostics.
Caution:
For the System Diagnostics on Models 100, 101, and 102
Pulse Generators, the Programming Software automatically programs
the Pulse Generator to 1.0 mA, 500
μ
sec, and 20 Hz. Patients whose
Pulse Generator output current, pulse width, and frequency are
normally set below these values may experience increased sensation,
coughing, a flushed face, or other effects. See the physician’s manual
for the VNS Therapy Pulse Generators
for a complete list of possible
adverse events.
